Do you think this is the roof of one of the caverns or this is the roof of a surface building??
I have been in a salt mine and it is really amazing. The one I went in had trucks and big equipment operating in it. All that equipment had to have been cut up and sent down the mine and then welded back together. As long as it stayed in the mine it would not rust but bring it back to the surface and it was gone in a short time.

Serious question ...
Why wouldnt the equipment rust in an extremely salty environment, but rapidly degrade when returned to the surface?
I imagine it must be because of moisture/humidity controls that the mines have in place, but don't know that for a fact.
The electrolyte (salt) is abundantly present, I'm assuming the oxygen content of the air in the mine is the same or similar to on the surface. That leaves the moisture component of corrosion, I think.
